racks may be selectively moved into operative position:

To eachl A'of the colored glass holdingY frames, 12, 13, and 14, a link member 19* may 1 be attached, preferably pivotally, and to'each such'link member a rack 2O is operatively secured. Vrl`his rack isslidably mounted in a vfloating frame'21. The floating rack 21 is connected bylink members 2 2 and 23 to rod member 24 towhich is operatively connected a solenoid 25. Onthe other side of the rack f there may be disposed similar link members V.26 and 27 and rod member 28 andrsolenoid 29 Vin all respects similar to the corresponding members' on the other side; Op'erativelyV mountedwith respect to the rack 20.is pinion 30`ofav length that may be engaged by racks' 31 and 32, disposed beneath rack20, racks 31 andy 32 being similarly yconnected to their respectivecolored glass holding frames 13 and k14,*y precisely as described for colored glass f holding frame 12. Y v

, AP 'nion 30 in turn ismounted on shaft 33 on which is secured gear` 34 which engages worm '35 on shaft 36, which is operatively connected v to a' motor not shown. Pinion 30 maybe y caused to" be revolved continuously in one direction. Energizing solenoid25 will draw inwardly the solenoid core 37, thereby causing rod24 to move to the right, which Y would shove frame 21 towards pinion 30 and `carries with it the rack 20 slidably mounted therein, so that pinion 30engages the teeth 38 of rack 20, and if pinion 30 is revolving counter-clockwise, manifestly the colored glass'frame 12 would be moved outwardly fandcausethe colored panels 18to be disposed beneath the reflectors 9; and when it is dei sired to retract the panels 18, solenoid 29 may be ,energized and'thereby draw inwardly soseparate solenoi'ds, 41 and 42 VV(on the opposite side solenoids not shown) may be similarly4 operated. AThe teeth 38 and 40 extend A onlypart of the lengthof the rack'so that i the! stopping of the movement'of the rack Y50 Y f frame13or the particular color of the colored tions of the panelsof these various frames.

-llongitudinally is automatic.

Obviously thestage maybe supplied with the white lightof theuncoloredbulbs in re- Y'iectors 9 or the stage may be supplied with -such colored light asv may depend upon'the fcolor of the glass in panels 18 of frame 12 yor the particular color of the glass in panels of glass in panels of frame 14, or any combinayManifestly,.ini'place of thel single acting solenoidsg25f and 29, af double acting' solenoid may be employed, in order to actuate frame 21 to and from pinion 30.

In Fig. 6, a modified form-of mounting and actuating means for rack 2O is illustrated. In this form a bracket 43 is pivotallymounted to oscillate on axis 44. A Bracket'43 is provided with a, depending .arm 45 integrally formed with bracket 43 to the arm 45, and rod 4G is pivotally Vconnected at 47 andat the other end rod 46 is-pivotally connected at 48 to a solenoid core 49.

Rack 20 is slidably mounted inguide ways Y 50, formed in bracket 43. j In this manner the actuating of solenoid core 49 swings bracket 43 upon aXis 44, thereby causing rack 20. to

4engage pinion 30.

Obviously, changes ,maybe `made infithe` Vforms, ,dimei-isions, and arrangement of the parts offvmy invention, jwi'thout `Vdeparting from the principle thereof, the abovesetting preferred formsof embodiment.V

forth only I claim bodyinga light holdingy frame; aplurality V.of

electric lights therein; avplurality o'fcolored glass holding frames,` each frame having panels of glass of a given colorV for each light; actuating means for said frames,I consisting of a rack operatively connected to each frame and pinion, said rackv and pinion i being relatively movable with respect to each other;and means whereby saidracks .mayV ,be selectively engaged by said pinion.

' 2. A device of the character described embodying a light holding frame; a plurality Vof electric lights therein; a plurality of colored glass holding frames, each frame having .panels of glass of'a given color for each light;

and actuating means for said colored glass holding frame consisting of -a rackoperatively connectedl to each of-said'frames, a

fra-me having vchannel "engaging: ways fin which said rack is Vslidably mounted, a sole-v connected to said -frame* and noidy operatively a pinion engageable by saidracks.
